High-pressure coolant unit
HPF Flex 70
Complete coolant management in one unit.
The HPF Flex 70 unit combines up to 70 bar and 65 l/min with pressure levels called by M-codes. One HPC outlet is standard; further outlets, spindle / sub-spindle flushing and the coolant gun are options*.

Why an accurately directed HPC jet changes cutting conditions
Flank-wear growth rate in internal boring
Production-representative ST52-3 trial: through-tool coolant at 25-50 bar reduced wear progression versus 20 bar flood cooling. Feed was also raised from 0.194 to 0.265 mm/rev in the HPC trials. [1]

surface roughness improvement (lower Ra) [2]
drill life with internal cooling in Inconel 718 [3]
These are independent trials with specific materials, tools and cutting parameters. They demonstrate HPC mechanisms and potential, not a guaranteed HPF Flex 70 result in another process.
What the unit adds to the cycle
-
1
Clean coolant
Filtration prepares the coolant for nozzles and through-tool channels.
-
2
Pressure on demand
An M-code calls the required level at the exact operation step.
-
3
Energy at the edge
The jet reaches closer to the tool-chip interface and supports heat removal.
-
4
Chip transport
Flow carries chips away and limits re-cutting in the machining zone.
